My invention consist-s in the eoi'nbinalion of a carrier which receives the inovablejnw and its nut with the inain parts of a wrench, whereby ihe movable jaw is tipped on the axis of the carrier when the wrench is used.

In the drawings, bar A is enlarged at e, and here bored to receive carrier B, and slotted ab o to admit movable jaw l). Carrier B is slotted to receive jaw l), and has a hole through it in wnich unt (Z.

Yihen the paris are arranged together, as shown, and the wreneh is applied to a pipe in the usual way,jaw D will rip on the axis of carrier B in sneh wise as to make my wrench a more effective instrument than any other known to nie.

v whereby my wrench is made stronger and more convenient for practical work than any pipew reneh known tio me.
